Good Morning, So yesterday, with lots of help from Micha and Martin, I got a vector file with a new column using bash. However when I try to run v.what.rast I get the continuous error
v.what.rast vector=contour_points_c...@permanent raster=dartmo...@permanent layer=1 column=rast_value "No record for category 553 in table <Contour_points_cats> No record for category 263 in table <Contour_points_cats> No record for category 668 in table <Contour_points_cats>" etc etc then the tool crashes without writing any values to the vector. I have checked that all points are both within the region and the raster extent and that the column type is correct for my float raster. Does anyone have any suggestions as to what I might be doing wrong? Many thanks for reading, Rebecca ________________________________ From: Micha Silver <[email protected]> To: Rebecca Bennett <[email protected]> Cc: Martin Landa <[email protected]>; [email protected] Sent: Wed, 9 June, 2010 10:12:28 Subject: Re: [GRASS-user] Re: Problems with v.what.rast On 09/06/2010 11:40, Rebecca Bennett wrote: > >Hi Martin, > >>I tried the command that Micha suggested v.db.addcol >map=contour_points_c...@permanent layer=1 >>columns="rast_value double precision" but this age the following error > > The quotes " " around the "rast_value DOUBLE PRECISION" are necessary. Just to check can we see the output of v.info -c Contour_points_cats You might also check that the points are all within the raster region. i.e.: v.info -g Contour_points_cats r.info -g Dartmoor1 g.region -p v.db.addcol Contour_points_cats col=rast_value DOUBLE PRECISION >>Sorry <DOUBLE> is not a valid option >>Sorry <PRECISION> is not a valid option > >>So through the GUI I added a column to the attribute table which gave >the command line out put >>v.db.addcol map=contour_points_c...@permanent layer=1 >{columns=rast_value double precision} > >>cheers! > > > > ________________________________ From: >Martin Landa <[email protected]> >To: Rebecca Bennett ><[email protected]> >Cc: Micha Silver ><[email protected]>; [email protected] >Sent: Wed, 9 June, >2010 9:37:14 >Subject: Re: >[GRASS-user] Re: Problems with v.what.rast > >>Hi, > >>2010/6/9 Rebecca Bennett <[email protected]>: >>> I added a column v.db.addcol map=contour_points_c...@permanent >layer=1 >>> {columns=rast_value double precision} (as my raster is a float), >then ran >>> with error > >>how did you get this command? > >>It should be > >>v.db.addcol map=contour_points_c...@permanent layer=1 >>columns="rast_value double precision" > >>Martin > >>-- >>Martin Landa <landa.martin gmail.com> * http://gama.fsv.cvut.cz/~landa > > > >>This mail was received via Mail-SeCure System. > -- Micha Silver http://www.surfaces.co.il/ Arava Development Co. +972-52-3665918
